maenn'r rnnmnan To all whom it may concern:

'Be it known that I, WILLIAM KAISLING,

a citizen of the United States, and resident the invention is to provide a simplified ter-" minal for this purpose, which may be readily and firmly secured to the head. of the magnet spool or other supports To this end, I so construct theterminal. that a single opening through the supporting member is sufficient both for the mechanical attachment and support of the terminal and for the passage of the electric conductor to be secured thereto. Preferably, this is done 1 by forming the port-ion of the terminal, to

be located within said opening, into a tube ofslightly greater length than thethickness of the supporting-member and flaringthe projecting ends into firm engagement with said member. Preferably also, the shank or projecting portion of the terminal is transversely bent soas to increase its rigidity.

The nature of the invention will be more fully understood upon reference to the following detailed description taken in connecits scope will tion with .the accompanying drawing, and be indicated in the appended claims.

Figure 1 of said drawing is a plan view of ablank from which the preferred terminal is formed; Fig. 2'isa partial vertical section of the preferred terminal, attached to its support; Fig. 3 is a perspective view of the same before attachment to its support; Fig. 4 is an elevation of a complete magnet spool and its supporting frame. showing a terminal in position; Figs.- 5 and 6 are erspective' views of modified forms ,of the invention; and Fig. 7 is a longitudinal section of another modification.

The preferred form of the invention, which is shown in-Figs. .1 to 4, is formed by punching out of a suitable sheet of metal stock a blank .of the general T-shaped outline of Fig. 1 and provided with notches 10-11-11 and an opening 12. The blank Specification, Letters Patent. Patented 1 2, 1911, Application filed March 2, 1908. Serial No. 803,871. v

able mandrel so oasto form a terminal; havmg a tubular portion 13 and a transversely bent or curved shank 14, the latter forming thus formed is then shaped about aIsuita continuation'of a portion of the wall ofthe former, as clearly'sho'wn in Fig. 3.' In

attaching the terminal to its supporting I member, the tubular portion 13 is. inserted lnto an opening in the member, and its ends areflared outwardly into engagement therewith so as to form a rigid mechanical connection. Preferably, the tubular portion is of greater length than the thickness of the support, so'that when the ends are flared,

they will firmly embrace the opposite sides of the supporting member, as illustrated in Fig. 2'. It will .be understood, however, that this, although desirable, is not absoe lutely necessary. The'ends of the tubular portion are flared or flanged by means of suitable tools acting .from opposite sides of the support, and the notches 10,permit ,the flange adjacent'to the'shank 14 to be readily and neatly formed. It will be apparent however that,.at the time of forming the tubular portion 13, either of its ends might be flanged, thus leaving only one end to be flanged after the insertion of the terminal into the aperture of the support. The transverse curvature of the shank 14 materially increases its rigidity over aflat shank.

The hole 12 and the notch 11 at the outer end of the shankprovide means for the ready connection of wire conductorsthe reto. This may be done by passing the end ofthe wire through the hole 12 and soldering it to the terminal, by wrapping it- 'about the shank at the notch 11 and solderi it,.or

by soldering it directly to the ea or the 7 shank without-employing the notch 11 'or opening 12. At the opposite end of the terminal, the connecting conductor is. led

through the opening in the tubular portion 13 and connected to the adjacentportionof the shank in any suitable manner. This-is preferably done as illustrated in Fig. 2.

where the conductor 0 extends from the right of the support 15 through the opening.

and is wrapped about the shank at the notches 11' and soldered in place,

Fi .4 illustrates one-of the more common applications of the use of the terminal. In

this figure, the support 15 constitutes the head .of a magnet spool 16. carried by an angle frame 17, which is notched at 18 to permit the passage of the terminal. It

. should be understood that this figure illus trates only one of the-applications of the invention, which is capable of use in many other and varied relations.

Obviously, the corstruct-ion above described may be modified in certain details without departing from the spirit and scope ofmy invention. For example,'in Fig. 5 I

have illustrated-a terminal'having a tubular portion 13 like that heretofore described, but having a flat shank 14. It will be noted that in this form, the shank is also reduced somewhat in width at the point 19 so as to permit the tubular portion 13 to be more perfectly formed. Again, instead of maintaining all the parts of the shank of equal width or curved as in the preferred form, the outer end may be made somewhat wider and turned up into tubular form, as shown at 14E in Fig. 6. Another form, which may be advantageously employed, is shown in Fig. 7. This form is made by taking a straight tube 20 and striking up a rib 21 thereon by causing a portion of the center of the tube to buckle outward, as illustrated. In thisform, the terminal is to be secured in place by flanging its end after insertion into the opening 1n the support,

as heretofore described.

It will be understood that, in practicing my invention, the tubular portions of the different forms of the invention need not be.

a portion of the tube wall beyond said support, the ends of the tubular portion being flared outwardly into engagement with opposite sides of the support to form a rigid connection therewith.

3. As an article of manufacture, an electric terminal comprising a tubular portion and a transversely curved shank-having the same degree of curvature as said tubular portion and having aperipheral width less than the periphery of said tubular portion and notches in the end of the tube at points adjacent to the edges of the shank.

4. The combination with a support, of an electric, conduct-ing terminal comprising a tubular portion extending through an aperture in said support and a shank forming a continuation of a portion of the tube wall extending outward from said support, the ends of the tubular portion being flared outwardly into engagement with the opposite sides of said support to form a rigid connection therewith while leaving an open- 4 ing through its center for the passage of an electric conductor, and the outer end of the shank being adapted for connection to a second conductor.

In witness whereof, I hereunto subscribe my name this 27 day of February, A. 'D.,
